Answer:
the answer is 100° because a triangle is a total of
180° and a straight line is also 180° so 180-160=20
and 60+20=80
and 180 -80 = 100 and the angle your looking for is a opposite from the angle that you just found
100
Explanation:
180-160 = 20
20+60=80
180-80= 100
it's opposite so the answer is 100
